Explanation:
consider the following problem: a box with an open top is to be constructed from a square piece of cardboard, 3 ft wide, by cutting out a square from each of the four corners and bending up the sides. find the largest volume that such a box can have. (a) draw several diagrams to illustrate the situation, some short boxes with large bases and some tall boxes with small bases. find the volumes of several such boxes. (b) draw a diagram illustrating the general situation. let x denote the length of the side of the square being cut out. let y denote the length of the base. (c) write an expression for the volume v in terms of both x and y.
The largest volume that the box can have is two cubic feet.
(a) Please see the attached graph created with MS Excel that show the variation of volume with the side length of the square cut out.(b) Please find attached the diagram created with MS Visio, illustrating the general situation. (c) The expression for the volume v in terms of both x and y is V = y²·x.Reasons:
Given parameters are;
The side length of the box = 3 ft.
x represents the side of the cut square, we have;
Height of the box = x
Width of the box, y = 3 - 2·x
length of the box, y = 3 - 2·x
The volume of the box, V = y²·x
Therefore; V = (3 - 2·x)²·x = 4·x³ - 12·x² + 9·x
At the largest volume, we have;
[tex]\dfrac{dV}{dx} = \dfrac{d}{dx} \left(4 \cdot x^3 - 12 \cdot x^2 + 9 \cdot x\right) = 12 \cdot x^2 - 24 \cdot x + 9 = 0[/tex]
Which gives;
4·x² - 8·x + 3 = 0
[tex]x = \dfrac{3}{2}[/tex], or [tex]x = \dfrac{1}{2}[/tex]
The value, [tex]x = \dfrac{3}{2}[/tex], gives the minimum volume of the box, given that [tex]\dfrac{3}{2}[/tex] is half the length of the cardboard, therefore;
y = 3 - 2·x
We get;
[tex]y = 3 - 2 \times \dfrac{3}{2} = 3 - 3 = 0[/tex]
Which gives;
[tex]V = 4 \cdot \left(\dfrac{1}{2} \right)^3 - 12 \cdot \left(\dfrac{1}{2} \right)^2 + 9 \cdot \left(\dfrac{1}{2} \right) = 2[/tex]
The largest volume that the box can have, [tex]V_{max}[/tex] is 2 ft.³
(a) The volume of boxes with their height, (side length of square being cut out) x are plotted on the attached graph.
(b) Please find attached the drawings representing the general situation.
(c) From the question analysis, we have;
The volume of the box in terms of x and y is V = y²·x
The volume of the box in terms of x only is V = 4·x³ - 12·x² + 9·x
The volume of the box in terms of y only is [tex]V = y^2 \times \left(\dfrac{3 - y}{2} \right)[/tex]

Explanation:
analyze the free-body diagrams (fbds) and place them in the indicated order according to the magnitudes of their net forces.
The order of the free-body diagrams (fbds) according to the magnitudes of their net forces are FBD 2, FBD1, FBD 4, and FBD 3.
This is evident based on the analysis described below:
FBD 1:
A = -30i + 40j;
B = 20j;
C = 20i + 10j;
D = -50j;
R = A + B + C + D;
R = -10i + 20j;
|R| = √ 10² + 20² => 22.36 N
FBD 2:
E = -40i;
F = 40i + 50j;
G = -50j;
R = E + F +G => 0;
|R| = 0 N
FBD 3:
H = -20i + 50j;
I = 60i + 10j;
R = H + I => 40i + 60j;
|R| = √ 40² + 60² = 72.11 N.
FBD 4:
J = -50i +30j;
K = 10i + 40j;
L = 50i + 10j;
M = -10i - 10j;
N = 10i - 50j;
R = J + K + L + M + N
R = 10i + 20j;
|R| = √ 10² + 20² = 22.36 N
Hence, in this case, it is concluded rust FBD 1 and FBD 4 are the same since they have a net force of 22.36N.
Therefore the lowest net force is FDB 2 and the highest net force is FDB 3.

which statement correctly explains why h2s is a stronger acid than water
Answer:
Sulfur (S) has a larger atomic size than oxygen (O), so H2S is a more stable, weaker base than H2O.
Sulfur (S) has a larger atomic size than oxygen (O), so H, 2, S, , is a more stable, weaker base than H, 2, O.
Sulfur (S) has a larger atomic size than oxygen (O), so H2S is a more stable, stronger acid than H2O.
Sulfur (S) has a larger atomic size than oxygen (O), so H, 2, S, , is a more stable, stronger acid than H, 2, O.
Sulfur (S) has a larger atomic size than oxygen (O), so HS– is a more stable, weaker base than OH–.
Sulfur (S) has a larger atomic size than oxygen (O), so HS, – , is a more stable, weaker base than OH, –, .
Sulfur (S) has a larger atomic size than oxygen (O), so HS– is a more stable, stronger acid than OH–.
I think the answer is the third one
It easily dissociates into ions in solution, releasing more hydrogen ions (H+). Therefore option A is correct.
[tex]\rm H_2S[/tex] (hydrogen sulfide) is a stronger acid than water because it readily undergoes dissociation in water to release hydrogen ions (H+).
This dissociation increases the concentration of H+ ions in the solution, leading to a lower pH value and stronger acidity. In contrast, water ([tex]\rm H_2O[/tex]) dissociates only to a small extent, resulting in a relatively lower concentration of H+ ions.
Therefore, [tex]\rm H_2S[/tex]'s ability to release more H+ ions makes it a stronger acid compared to water.
Therefore option A is correct.

deterioration of buildings, bridges, and other structures through the rusting of iron costs millions of dollars every day. although the actual process also requires water, a simplified equation (with rust shown as fe2o3) is:
Rusting is a very expensive process to humans and is represented by the simplified equation of: 4Fe + 3O₂ → 2Fe₂O₃ .
At the basic level, rust occurs when iron comes into contact with air (oxygen) and they both react to form Iron Oxide which is the chemical name for rust.
The equation is:
Iron + Oxygen → Iron Oxide
4Fe + 3O₂ → 2Fe₂O₃
In conclusion, the simplified equation for rust is 4Fe + 3O₂ → 2Fe₂O₃.
